#===================================================================
# Makefile to synthesize rekonstruct, adapted from David Burnette's
# System09 Makefile
#
#  This makefile will build John Kent's entire System09 project 
#  (RTL synthesis and monitor ROMs) and even download the final 
#  bitstream to the prototype board.
# 
#  You can use Xilinx ISE interactively to add new RTL source files
#  to this project.
#
# Usage:
#  Use 'make help' to get a list of options.
#
# Dependencies:
#  Depends on makefile fragments in the 'MKFRAGS' directory.
#
